I've been on a real Chimay kick lately since the weather's been warming up. I'm usually a Guinness guy, so don't care much for lagers, pilsners, etc., but few things beat a cold Chimay Red on a 110degF day. They're pretty similar to red ales and have a slight fizz to them.

Incidentally, each one of those is between about 6 to 9% depending on which one you get (and I seem to remember that they have one that's around 12%), so the bang for the buck is good.
